Thanks for opening @DanAtkinson. This change is probably better handled in the DocsGenerator, to deduplicate the overloaded methods when generating the asciidoc labelled list. Would you like to tackle this? I think it would just need a change in

elasticsearch-net/src/DocGenerator/AsciiDoc/GeneratedAsciidocVisitor.cs

Line 313 in 1eb3928

foreach (var item in visitor.LabeledListItems.OrderBy(l => l.Label)) labeledList.Items.Add(item);

to distinct by Label too.

@russcam Thanks. I'll take a look. I haven't used the DocsGenerator but it should be fairly straightforward to run, change, test, and verify.

Doc generation can be run from the build script in the root of the repository

.\build documentation
